My Xperia X10 stopped charging a little while back so i took it to my network provider to be sent for repair under warranty. 2 weeks later i received a text explaining it was back at the shop. I went to pick it up and found an Arc in the box! Im v.happy with it, the x10 done my head in. The arc is a lot better, but can anyone shed any light on why this happened?? Is it a mistake on their part??
